“…Nanoparticles due to their small size have exciting physicochemical properties, such as a high specific surface-to-volume ratio, a size similar to the size of biomolecules allowing for their greater mobility and passing through the cell biological membranes 8 . Morphology and specific surface area affect the antibacterial activity, therefore, it is necessary to synthesize a material with a novel morphology having a higher amount of adsorption sites and surface area 9 – 11 . Thus, verifying the morphology of the materials and hence their specific surface area can show great potential for bioapplication because the properties can be tuned and improved.…”

The aim of our work was the synthesis of ZnO nano- and microparticles and to study the effect of shapes and sizes on cytotoxicity towards normal and cancer cells and antibacterial activity toward two kinds of bacteria. We fabricated ZnO nano- and microparticles through facile chemical and physical routes. The crystal structure, morphology, textural properties, and photoluminescent properties were characterized by powder X-ray diffraction, electron microscopies, nitrogen adsorption/desorption measurements, and photoluminescence spectroscopy. The obtained ZnO structures were highly crystalline and monodispersed with intensive green emission. ZnO NPs and NRs showed the strongest antibacterial activity against Escherichia coli and Staphylococcus aureus compared to microparticles due to their high specific surface area. However, the ZnO HSs at higher concentrations also strongly inhibited bacterial growth. S. aureus strain was more sensitive to ZnO particles than the E. coli. ZnO NPs and NRs were more harmful to cancer cell lines than to normal ones at the same concentration.

“…Hexagonal objects are also identified; they may be correlated to the splits observed on the XRD pattern (Figure AM2). Anandhan et al reported similar hexagonal sheets when CdOx nanostructures were prepared in the presence of pyridine as the capping agent (Anandhan et al, 2019). In some cases, some aggregates are formed, probably due to the melting of adjacent crystals during the calcination step.…”

“…This is consistent with the TEM observation that shows two phases or morphology of crystals (see section 3.1.4.). In the case of pyridine-capped CdOx crystals (which have some hexagonal nanostructures), the planes were also identified at very close values of 2q (Anandhan et al, 2019).…”

Photocatalysis is one of the promising processes for developing greener fuels. This work compares a new liquid Cd-based diacetate and CdOx nanoparticles for photo-desulfurization of diesel. Various tools, including XRD, XPS, TEM, 1 H& 13 C NMR, FTIR, reflectance, and photoluminescence, were used for char-acterizing the materials. Different parameters, such as irradiation type, catalyst dosage, oxidizing agents, and solvent extraction were applied. The results showed that, under visible light irradiation with a linear halogen lamp (LHL), Cd diacetate reveals promising sulfur removal (98.5%) for 2 h compared with CdOx NPs (97.7%) for 3 h in the presence of H 2 O 2 and acetic acid as oxidizing agents and acetonitrile as a solvent. Under sunlight, sulfur content decreased from 11500 ppm to 65 ppm (removal exceeds 99.4% for the Cd diacetate against 98.0% for CdOx NPs) with high-quality properties (aniline point: 91.8 C, diesel index: 79.8). The photo-luminance activity of Cd diacetate (low intensity) allows reducing electron/hole pair recombination, which maintains stable photocatalytic activity with enhanced visible light elimi-nation of organosulfur compounds for economical, clean fuel production associated with pollution control. The catalyst recycling and the spontaneous regeneration of the solvent make the process very attractive. Cd diacetate was successfully recycled over six cycles.
